Hello, I've tried Adobe Acrobat and lots of other pdf-viewers, all the same: I cannot open or download any pdf from a website... When trying to open the pdf an error-message occurs (I try to translate from German): "file could not be downloaded. Save the file in your local storage/memory and try to open it afterwards". (and actually I have no clue how to save or download it when instantly after pressing/clicking this error message occurs^^ (even if I press a long time on the pdf, no menu appears offering a download (just one to save the website as a pdf)) Opening and saving pdfs works fine from other apps or from mail-accounts, and - I just tried it for the first time - as well from the chrome-browser (I was asked then if I'd like to use adobe or any other pdf-reader to open) As I'd like to stick with Firefox and don't want to change to any other browser, has anyone a solution or hint? Thanks and Regards, Sholto Using: Android 10, Firefox 68.11.0 and a Sony Xperia XZ2 compact
